SLlClNG-MACHINE AND FEED MECHANISM SPECIFICATION forming part of Letters Patent No. 626,764, dated June 13, 1899.

Application filed February 25,1898. Serial No. 671,555. (No model.) 7

- provement in Feed-Motions for Slicing and other Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a feed-motion for a slicing or other machine, the same embodying a traveler or pushing'device which is operated by the traction of a reciprocating rod or shaft on which said traveler is freely mounted, said traction being effected by the opera tion of a movable member, the traveler receiving motion at intervals from said reciproeating shaft in only advance direction, the construction of said parts avoidingthe em ployment of a rack or toothed bar to effect said advance of the traveler.

Figure 1 represents a side elevation of a slicing-machine embodying my invention. Fig. 2 represents a partial plan view and a partial horizontal section thereof. Figs. 3 and at represent front views of different portions thereof. Figs. 5, 6, 7, S, 9, and 10 represent views of detached parts, on an enlarged scale, the same being partly in elevation and partly in section. Fig. 11 represents a perspective view of one of the cams.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a rotatable cutter, the same consisting of the circular or other shaped frame 13 and the blades 0, secured thereto, said frame being mounted by its rim D on the stationary open frame E, the latter having peripheral rims F and G, between which the rim D of the frame B is adapted to rotate. Interposed between the rims F and Gand the rim D are balls H and J, which are freely seated in grooves in said rims, thus providing ball-bearings for said rims, whereby the cutter rotates with great freedom and smoothness.

K and L designate rods or shafts whose surfaces are untoothed or preferably smooth and which are mounted at one end on the frame E and at the other end on the bracket M, the rod K being stationary and the rod L being movable in the direction of its length both on M the frame E and bracket M, it having on the end adjacent to the frame Ethe shoulders N- and P, which are adapted to be engaged at intervals by the, cams Q Q, which are mountfreely enters the trough U, the latter being supported on the lower portions of the bracket M and frame E and extending parallel with the rods K and L below the same, the forward end of said trough being open and located near the back of the cutter A, so that as the traveler advances it carries the hanger T with it, and the material to be sliced or cut, placed in the trough U, is presented to the blades of the cutter.

On the rods, between the eyes S S of the traveler, are the annuli V,'which freely embrace said rods and have tongues W on the inner sides thereof, said tongues abutting against the shoulder X within the traveler, the adjacent faces of the eyes S being oblique to permit the annuli to be pressed against them in similar direction, as most plainly shown in Figs. 5 and 8. Bearing against the annuli are the springs Y,whereby they occupy oblique positions on or acute angles to the rods, and their inner. peripheries bite the surfaces of said rods, so as to take firm hold thereof.

The tongues \V of the annuli have bearing against them the lower limb of the lever Z, which is mounted on the traveler, so that when said lever is operated it bears against the tongues \V and presses them forwardly, whereby the annuli are moved from their oblique positions to those of a right angle, ornearly so, whereby their bite on the rods is overcome, and the traveler may be run back on the rods without interference of the annuli.

The operation is as follows: The trough is supplied with an article to be sliced-whether bread, smoked or dried beef, or other food the hanger being removed from the cutter the length of said article. The cutter is rotated and advancing motion imparted to the rod L by the action of the cam Q against the shoulder N. Owing to the bite of theannulus on said rod the traveler is coupled by said annulus with said rod and so advances with the latter the distance of motion imparted to the rod, and with it the hanger T, which, pressing against the article in the. trough, moves it .ther motion, and with it the hanger, so that the article is moved a further extent and a fresh surface of said article presented to the cut-- ter. Projecting rearwardly from the frame E is a bolt E, which is so disposed that it is in the path of the upper end or handle portion of the lever Z, so that when the carrier has advanced to full extent said leverstrikes said bolt and releases the annulus S, whereby the feeding motion ceases and the hanger T is prevented from being engaged by the cutter.

Owing to the screw or bolt Q which carries the cams Q Q, the latter may be adjusted with precision relatively to the shoulders P on the rod L for cutting different thickcal portion of the pusher is open or separated,

forming teeth, between which are passed the tines of the fork T on which the article to be fed is impaled, thus preventing the rotation or improper displacement of said article, while, however, not interfering with the advance motions of the same by the action of the pusher. vThe tines are supported on the rear end of the trough and passed through slots therein and provided with a handle T for evident purposes. It will be noticed that two rods or shafts are employed for supporting the traveler, and each is provided with an annulus, one of said rods being stationary, as has been stated. Now when the movable rod is returned it passes freely through the annulus thereon,but the otherannulus,which is on the stationary rod, bites the latter and so prevents return of the traveler with said movable rod.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A smoothly-surfaced shaft, means for imparting reciprocating motions thereto, a traveler freely mounted on said shaft,an obliquelyarranged annulus carried by said traveler and loosely fitted on said shaft, and means for forcing said annulus into engagement with said shaft. v

2. A movable shaft, means for operating the same in opposite directions, atraveler freely mounted on said shaft, an obliquely-arranged annulus carried by said traveler and means for forcingsaid annulus into engagement with said shaft, in combination with a stationary shaft having an obliquely-arranged annulus loosely fitted thereon and carried by said traveler and provided with means for forcing it into an engagement with said secondary shaft.

3. A sliding shaft, a rotating member, reversely-pitched cams on said member adapted to impart reciprocating motion to said shaft, a traveler freely mounted on said shaft, an obliquely-arranged annulus carried by said traveler and loosely fitted on said shaft, and means for forcing said annulus into engagement with said shaft.

4. A shaft, means for imparting reciprocating motion thereto, a traveler freely mounted on said shaft, an obliquely-arranged annulus carried by said traveler and loosely fitted on said shaft, means for forcing said annulus into engagement with said shaft, and a lever pivoted on said traveler and adapted to engage a side of said annulus for releasing the latter of engagement with said shaft.

5. A shaft, a support therefor, means for im parting reciprocating motion to said shaft,a traveler independen tly mounted on said shaft, an annulus carried bysaid traveler and freely fitted on said shaft and a spring bearing against said annulus, said traveler having a shoulder with which one side of the annulus abuts, whereby said annulus is adapted to engage in oblique direction with the surface of said shaft.

6. A movable shaft, a traveler mounted thereon, an obliquely-arranged annulus carried by said traveler and freely fitted in said shaft, and means for forcing said annulus into engagement with said shaft, in combination with cams adapted to engage said shaft in opposite directions, a rotating member on which said cams are supported, and a bolt engaging said cams whereby they are adjusted toward and from each other.

7. A frame having the bolt E projecting therefrom, in combination with a sliding shaft on said frame and means for advancing the same, a traveler on said shaft, an annulus on said carrier adapted to engage said shaft and alever carried by said traveler and adapted to engage the side of said annulus, said bolt being in the path of said lever and engaging said lever when the traveler approaches the ends of its course whereby said annulus is released and its biting action and the feeding motion are automatically stopped.
